Handling and rendering dates that may/not exist - mongodb

Question

I have schema similar to this:
Schema.Adviser = new SimpleSchema({
"firstName": {
type: String
}
});
Schema.Orders = new SimpleSchema({
"adviserId": {
type: Object
},
"period": {
type: Date
},
"order": {
type: Number,
min: 0
}
});
I need to render a table like this:
first name | January | February
Bob | 1 | 0
Bill | 0 | 1
Each value is an input field that is editable.
If for example there is no order record for Bob in January I need January to still render, ideally with a 0 such that someone can add a January order.
Something like this:
months is an array of months to be shown. Each follows the format: Mon Feb 01 2016 00:00:00 GMT+0000
{{#each month in months}}
{{#each getOrders}}
{{#if equals month period}}{{order}}{{/else}}0{{/if}}
{{/each}}
{{/each}}
Not only can I not get this to work, but before spending much more time trying to debug the issue I'm wondering if this is really the best way to do this.
Any advice?
Many thanks

Answer 1

var months = ['Jan', 'Feb', 'Mar'];
var advisors = [{
ID: 1,
name: 'Bob'
}];
var emptyMonthArray = [0, 0, 0];
orders = [{
advisorID: 1,
period: new Date(),
order: 3
}];
function getAdvisors() {
var returnArray = [];
advisors.forEach(function(a) {
var returnObject = {
name: a.name,
monthData: emptyMonthArray.slice(0)
};
orders.forEach(function(o, i) {
if (o.advisorID === a.ID) {
returnObject.monthData[o.period.getMonth()] = o.order;
}
});
returnArray.push(returnObject);
});
return returnArray;
}
console.log(getAdvisors());
I think a bit cleaner way of doing this is to make a getAdvisors helper that would process and transform the data and return something like
[
{name:'Bill', monthData:[0,1,0,2,...]},
{name: 'Bob', monthData:[...]}
]
which much neater could be expressed in a Template something like this:
<tr>
<th>Name</th>
{{#each month in months}}
<th> {{monthname}}</th>
{{end each}}
</tr>
{{#each advisor in getAdvisors }}
<tr>
<td>{{name}}</td>
{{#each monthData in advisor}}
{{td>{{this}}</td>
{{end each}}
</tr>
{{end each}}
EDIT: added a fiddle https://jsfiddle.net/runjep/1xrp1gfq/ (this will only work the first 3 months of the year ;-) after that you would have to add 'Apr',...
EDIT again using your fiddle https://jsfiddle.net/runjep/0qy34pfe/3/
Unfortunately meteorpad is down so here's what I think will work.
{{#each advisers}}
{{firstName}}
{{#each monthData}}
{{this}}
{{/each}}
{{/each}}
